To all whqmjt may concern:.

Bait known that I, FRIEDRICH Gasman, a subject of the German Emperorsiding at N achodstrasse 39, Berlin, (irermany, fi-have invented certainnew and useful Imrovements in- Ball-Bearings, of which the ollowing is aspecification.

The-present invention relates to a ballb ea consisting of an'inner ring,an outer ring smaller balls between the individual large balls and asupportingdevice for the balls.

The invention consists substantially in the constructive formation ofthis supporting device in such a manner that it can be made by stampingin the simplest manner and without complicated swages and be puttogather, without the help of screws, rivets and the like.

.20 ballrbearing is represented in the drg wingin figures.

1 is an elevation partly in section;

A..A of I; 3'shows a develo ment of the sup orting devicealone, and ig.4 shows one bridge of this sup orting device.

-The-ball -bear1ng consistsloi the inner ring f, the outer ring 9 andthe large carrying balls 6 situated between them. Between 5 80 theseballs 6 there are smaller balls (2 which serve. for convertingtheslidinfilfriction between the large balls into ro 'ng friction. Thesupporting device consists of two sheetmetal rings a which cover'theannular space 36 between the two b'all races and'which are connected bya number of cross-pieces or brid es arranged at rightangles to them. Theridges consist of two bars 0 beside one another which have a hole in thecenter and 40 carry small pins e at their ends. The rings a and re--arge balls between the two rings,-

an .a longitudinal section in the planeright angles to said fiat ringsand passing have slots corresponding to these ins eand can therefore beplaced on the bridges c, whereupon the little pins e are bent over; Thesmall'balls d are ar'ra ed between the two bars a of each brid e. heholes in the bars 0 are splayed an the .edges It of the. holes serve asguides for the small balls. What I claim as'm invention and desiretosecure b Letters atent"is:-- l

1 A bal -bearing comprisingin combination an inner ring, an outer flarg'e balls in the annular space between said rings, two flat ringshaving a plurality bf slots arranged between said rings coverin saidballs in said annular space, a plura ity of'bridges having holes andsmall ins on their ends arranged between said alls at right angles tosaid flat rings, said pins-passing through said slots and connectingsaid flat rings together, and small balls in said holes between,saidlarge balls.'

2. A ball-bearing comprising in combina tion an inner ring, an outerlarge balls .in the annular space between 881d rings, two

fiat rings having a plurality of slots arrange (:5 between said ringscove said balls in said annular space, a plura 'ty of bu in pairsarranged between said alls and at through said slots connecting saidflat rrugs together, said 'bars having holes at their centers being slayed about the holesand havin small balls in said holes be tween saidlar e alls.
